These are pretty good. Better warm than room temperature. I think the spices need to be turned up. If I make it again, I might at ginger or orange zest.
I used puff pastry from Trader Joes, which came packaged as 2 9x9-inch sheets. I rolled it out to 12x12, but cut it into 3-inch squares, so I yielded 16 mini turnovers out of one sheet... 32 total.

AWESOME! I just finished eating this for a great lunch. I only wanted to use what I had on hand. So I pulled 1 chicken breast out of the freezer and tossed it in a ziploc bag with the marinade. I didn't have dried onion, rosemary, or parsley, and I don't care for oregano. So I replaced them all with a tsp of Mrs. Dash table blend. I halved the red pepper flakes, used 2 tsp fresh minced garlic, omitted the salt, and kept the remaining ingredients as written. Since my chicken was frozen I left it out instead of putting it into the fridge. After an hour I added 1/2 onion and 1/2 orange bell pepper, both chopped. Then I left it to marinate for another hour. I baked it in a covered Corningware dish, instead of baking uncovered. I preheated the oven to 350 degrees, strained the marinade into a small sauce pot, and put the chicken, onions, and peppers into the baking dish. Baked for 40 minutes, covered the whole time. While that was in the oven, I reduced the marinade on a low simmer for 30 minutes (reduced volume by half.) The balsamic vinegar became a bit sweet and the tangy-ness mellowed out. Delicious! I wisked in one tablespoon of extra-virgin olive oil to use it as a salad dressing. I topped a large bowl of mixed greens with a few tablespoons of the warm "dressing," letting the greens wilt a little bit. I topped it with half of the peppers, onions, and chicken. yum! Next time I will probably cut the vinegar just a tad and replace it with water or OJ. Thanks to R.Upchurch!

Perfect! The ingredient proportions are exactly what I was looking for. I used Fage 0% fat plain greek-style yogurt instead of vanilla yogurt to make it a bit healthier. Also used frozen mixed berries. It came out to be either a big serving for one person or smaller amount for 2 people. Thanks!
